Abstract

PURPOSE:To obtain a carpet having excellent water repellent property, free from falling-off of pile and rich in restoring force by making sol solution of a vinyl chloride resin sufficiently absorb into a carpet body in which pile is set into a base cloth, removing excess sol solution and then subjecting the treated pile to heat curing. CONSTITUTION:A carpet body in which pile 2 is set into a fiber base cloth 1 is dipped in a sol liquid of vinyl chloride resin till the pile 2 absorbs the sol liquid sufficiently and then excess sol liquid impregnated into the pile by a press roller is removed and the sol liquid is sufficiently permeated into the pile fiber and the treated pile is subjected to heat curing and as necessary a packing material 10 is pressed to the back face of the carpet to provide the aimed carpet having excellent restoring force of pile and water repelling property and especially suitable for shoe sweeping mat. Furthermore, the sol can sufficiently be absorbed into the pile fiber by moving the carpet body into the sol liquid of vinyl chloride resin in a zigzag direction.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for producing a carpet with excellent water-wetting and oil resistance by impregnating a sheet body made of a fiber product such as pile with vinyl chloride resin. The present invention also relates to a method for producing a mesh-like fibrous shoe-wiping mat that has excellent water and oil resistance.

[Conventional technology]

In conventional carpets, liquid spilled on the carpet soaks into the piles and stains them, and the piles quickly fall down, resulting in poor appearance. Therefore, in order to make the pile part hydrophobic and oily, there is a method in which the pile part is made to have hydrostatic oiliness by spraying or containing a substance that has hydrostatic oiliness in the pile as a post-treatment (Special Publication Publication No. 63). -35243, 36
No. 242).

Furthermore, wire mats are generally used as mesh-like shoe cleaning mats, and fibrous mats such as synthetic fibers have not been used due to problems such as toughness and abrasion resistance.

[Problem to be solved by the invention]

However, if the pile carpet is treated as described above, the oil will only adhere to the surface of the pile, and the anti-slip effect will soon disappear.

Also, even if you do this, the pile is made of twisted synthetic resin fibers such as nylon and acrylic, so it has poor absorption of chemicals and does not make the pile itself strong, so it is not possible to eliminate the collapse phenomenon. I could not do it.

In view of the current situation, the inventors of the present invention have attempted to provide a carpet in which the pile itself has water contact properties and which semi-permanently eliminates the falling down phenomenon.

In addition, wire mats are prone to corrosion due to oxidation.
It has drawbacks such as being slippery and dangerous when wet.

Furthermore, the m-male mat had the same problem as the pile carpet described above.

The present inventor has developed a method by impregnating a sheet body, which is made by integrating a base knitted fabric with a number of fiber stripes and a mesh-like knitted fabric through thread-like pillars of slightly hard thin fibers, with a sol solution of vinyl chloride resin. The objective was to provide a shoe-wiping cloak that is not only strong and abrasion resistant but also has excellent resistance to water and oil, and which is also lightweight and inexpensive.

[Means to solve the problem]

In order to achieve the above object, the present invention has the following configuration.

A carpet body K in which piles 2 were planted on a base fabric 1 was immersed in a vinyl chloride resin sol solution S until the piles 2 absorbed the sol solution S, and the excess sol impregnated into the piles 2 was removed using a press roller 3. Thereafter, the carpet body K on which the pile 2 has been raised is heated to harden the impregnated sol.

A backing material may be crimped onto the back side of the carpet body.

Further, as a second method of the invention, the carpet body K, in which the pile 2 is planted on the base fabric 1, is moved in a meandering manner in the vinyl chloride resin sol liquid tank 4 to allow the pile 2 to sufficiently absorb the sol liquid.
After removing the excess sol impregnated into the pile 2 with a press roller 3, the pile 2 is backed on the back side of a raised carpet body.

Further, the shoe cleaning mat body has the following configuration. A base knitted fabric 21 made of synthetic fibers and a mesh-like knitted fabric 22 are combined with a large number of thread-like pillars 2 of slightly hard thin fibers.
The sheet body A, which is integrally formed through 3, is immersed in a sol solution S of vinyl chloride resin to be impregnated with the sol solution S, and then the sheet body A is heated and cured.

In this case, after removing the excess sol S impregnated into the sheet body A with the press roller 25, the sheet body A may be heated and cured.

[Effect]

Since the present invention has the above configuration, it has the following effects.

The carpet body K is immersed in the sol liquid layer 4 of vinyl chloride resin.The pile 2 is sufficiently impregnated with the sol liquid S, and then the carpet body is pressed with a press roller 3 to remove the excess sol impregnated into the pile 2. Since the sol liquid is allowed to penetrate into the fibers of pile 2, the sol liquid is completely absorbed into the pile 2. Then, the pile 2 is stiffened in a raised state due to heating during backing after raising the fallen pile 2.

When immersed in the sol solution, if the sol solution is meandered in the sol solution tank 4, the sol solution will be easily absorbed into the pile 2.

Since the present invention regarding the shoe cleaning mat has the above-described structure, it has the following effects.

Since the base knitted fabric 21 and the mesh-like knitted fabric 22 of the sheet body A are knitted with fibers, etc., they have good absorbency, and the sol solution S of the vinyl chloride resin easily impregnates the entire sheet body A.

The sol solution S also impregnates between the many thread-like pillars 23, and after the sol solution S dries, the thread-like pillars 23 become complete standing walls, so when used as a shoe-wiping mat, dirt on the soles of shoes can be removed. It becomes easier to drop.

The sol solution S is impregnated up to the heath knitted fabric 21.
Therefore, there is no need to create a new backing as a base for the mat body, making it possible to improve workability and reduce costs.

Reference numeral 11 denotes a heater which dries and hardens the carpet K transferred by the belt conveyor 8 with hot air at 175 to 190°C.

The carpet body K thus dried is cooled.

Next, an embodiment of the method of inventing a shoe-wiping cloak will be described with reference to the drawings.

A is a sheet body which is made up of a base knitted fabric 21 and a mesh-like knitted fabric 22 knitted from synthetic fibers or the like.

The base knitted fabric 21 and the mesoche-like knitted fabric 22 are integrally knitted from the upper and lower ends of a large number of thread-like columns 23 made of slightly hard thin fibers.

24 is a sol liquid tank containing a sol liquid S of vinyl chloride resin, in which the sheet body A is immersed.

Reference numeral 24a denotes a baffle bar that extends inside the sol liquid tank 24, and the sheet body A meanders between these bars so that the sheet body is immersed in the sol liquid S for a long time. The degree of impregnation of the sol liquid is improved.

〔Effect of the invention〕

Next, the effects of the present invention will be explained.

In the method of the present invention, the pile 2 planted on the base fabric 1 is not only soaked until it completely absorbs the solized vinyl chloride resin liquid, but also the sol liquid is soaked into the pile fibers by the press roller 3. Therefore, the sol liquid is absorbed up to the base of the pile 2, and even if the pile 2, which is raised when completed, is trampled, it will immediately return to its original state.

In addition, since the hardened vinyl chloride resin is adsorbed in the pile 2, it has excellent water contact properties, making it difficult for water to accumulate on the mat, making it particularly suitable as a shoe-wiping mat.

In addition, since the degree of adhesion of the pile 2 to the base fabric 1 is increased, it is possible to prevent the pile from coming off, and since the base fabric 1 is also impregnated with the solized vinyl chloride resin, no special backing work is required. This results in improved workability.

When the carpet body K is moved in a meandering manner in the sol liquid tank 4, the carpet body K expands and contracts, so that the contact area between the carpet body and the sol liquid increases, and the sol liquid is evenly impregnated into the carpet body K. .

When crimping the backing material to the back side of the carpet body, the crimping tends to be insufficient and the pile 2 tends to fall off.
In the method of the present invention, since the sol-like liquid is also adsorbed on the back surface of the carpet body, the backing layer 10 is easily absorbed and the pile 2 can be prevented from falling.

Next, the effects of the shoe cleaning mat invention will be explained.

Since the mat produced by the method of the present invention is a textile product, it is lightweight, easy to transport, and easy to clean.

Since the entire mat body is impregnated with vinyl chloride resin, it has excellent water-repellent properties, making it easy to wash off stains and remove water droplets.
